Description

[0001] The invention relates to a container locking device on a vehicle for locking a container to be transported on a loading area of ​​the vehicle with a corner fitting, comprising a locking housing, a locking bolt, and a drive, wherein the locking bolt has a shaft and a locking head which, in the unlocked state, can be inserted through an opening in the corner fitting of the container and, in the locked state, secures the container via projections engaging behind the opening of the corner fitting. The locking bolt is mounted with its shaft in the locking housing so as to be both axially displaceable and rotatable about its axis. A wedge slide is mounted laterally in the locking housing, i.e. perpendicular to the axis of the locking bolt, so as to be reciprocable and drivable by the drive, and the wedge slide has a run-on slope.which engages the locking bolt during the lateral movement of the wedge slide and imparts an axial movement and a rotational movement of 90° to the locking bolt. Furthermore, the invention relates to a container locking method that can be carried out using the above-mentioned device.

[0002] Such a locking device for containers on a vehicle is known from EP 1 075 400 B1. A diaphragm accumulator drive is proposed as the drive for the linear movement. This drive is only held in its working position when pressurised air is applied and is returned to its released position by a spring when the pressure drops. Thus, with this locking device, it is necessary to first activate the drive by applying compressed air before loading the vehicle in order to bring the locking device into its unlocked state. The container can then be loaded with its corner fitting via the unlocked locking head. When the pressure is released, the diaphragm accumulator is then spring-loaded and returned to its basic position, causing the locking bolt to rotate and lower.

[0003] Based on this, the not yet published DE 10 2021 112 894 of the same applicant applies for a container locking device for locking a container to be transported on the loading area of ​​a vehicle with a corner fitting.

[0004] DE 102 02 190 A1 describes a container locking device similar to EP 1 075 400 B1, but in which the locking bolt on its shaft does not have a tangential, rising recess on its circumference, but rather two pairs of cams arranged laterally one above the other and offset. Furthermore, the device can have an additional safety device that prevents the pivot pin from being pulled out vertically toward the container in all positions of the locking bolt (pivot pin). A disadvantage is that the additional safety device must be set and released manually.

[0005] Furthermore, DE 10 2006 002 654 A1 discloses a device for actuating a locking mechanism of a locking head with a corner fitting of a container. This device comprises a pneumatic piston-cylinder arrangement with which an extendable and lowerable claw of the locking head can be moved from a retracted position to an extended position and from there to the locking position and back again. Here, too, a supplementary lock is not provided, so that the device is held in the locking position solely by the pneumatic drive. A technically similar design with a hydraulic actuation is known from DE 20 2008 011 526 U1.

[0006] Horizontal locking devices are also known on gooseneck trailers. They are used at the frontmost position on the trailer in the direction of travel to secure containers with gooseneck tunnels in their forward position from lifting or slipping. At this position, there is not enough space below the container to accommodate the so-called "twistlocks" commonly used to secure standard containers to a trailer, along with the required substructure (crossbeams). However, since using the gooseneck chassis with so-called high cube containers with gooseneck tunnels provides approximately 10 to 14 cm more usable loading height without exceeding the internationally frequently prescribed total loading height of the semi-trailer of 4 m, this considerable effort is justified.

[0007] In order to be able to load containers without a gooseneck tunnel onto such gooseneck semi-trailers or chassis, so-called double locking systems are known. In these systems, a console that can be pivoted around a horizontal axis and folded down to the position of the locking bolt so that this console can be locked to the locking bolt and offers a raised support surface for containers without a gooseneck tunnel. This console is usually provided with a conventional twist lock for locking the container. One such double locking system is known, for example, from Jost-Werke GmbH, Siemensstraße , 63263 Neu-Isenburg, under the designation FB 88-14V. Such a double locking system is also described in EP 0 934 848 A2 and, in a further development, in DE 10 2014 218 891 A1.

[0008] EP 3 666 591 A1 describes a container locking device with horizontal and vertical locking options that can be operated independently of each other.

[0009] A disadvantage, however, is that the horizontal locking devices, especially those used on gooseneck trailers at the front of the trailer for securing containers with gooseneck tunnels, must be manually locked and released. This means that the familiar horizontal locking devices must be manually operated before and after unloading. This not only consumes time but also poses a significant risk to the driver.

[0010] Therefore, DE 20 2010 000 387 proposes a semi-automatic horizontal locking device in which the locking bolt is spring-loaded in the direction of the transport state and has a run-on bevel at its end facing the corner fitting. The locking bolt has a first locking position for the transport state of the locking bolt and a second locking position for the retracted unloading state, and a sensing device is provided for determining the loading state of the loading area. For unloading, the locking bolt is manually moved into the unloading state and, after unloading, the locking bolt is released by the sensing device. This enables automatic locking and latching of the container during loading. The sensing device arranged next to the locking bolt allows the detection of a container in the loading position.The disadvantage is that the sensing device is designed in many parts and, due to its complexity, can lead to malfunctions, for example in the case of insufficient maintenance, and the locking device is costly to manufacture.

[0011] US Patent No. 5,575,599 discloses horizontal locking devices that are triggered by the weight of the container being loaded. These devices are not locked in the locked position and therefore offer little safety in the event of accidents or particularly heavy loads. A similar system is known from US Patent No. 2015 / 0232015 A1.

[0012] DE 197 20 238 A1 describes a container locking device with a rotationally driven locking head, in which a horizontally movable plug pin for so-called gooseneck container chassis is simultaneously extended laterally via a gear segment with the rotational movement.

[0013] DE 10 2004 045 665 A1 shows a cross member for frontal installation in a chassis, in which a twistlock and a horizontal plug pin are arranged so as to be movable independently of each other.

[0014] JP 2011-051559 A describes a container chassis with horizontal and vertical locking means that can be actuated by means of actuating cylinders.

[0015] Based on the prior art mentioned at the outset, it is the object of the invention to provide an actively driven container locking device or a container locking method which, in addition to the locking device engaging from below into the container corner fitting, also makes horizontal locking for gooseneck containers possible.

[0016] This object is achieved with a container locking device according to claim 1 and a container locking method according to claim 9.

[0017] By additionally mounting a horizontal locking bolt in the locking housing so that it can be moved axially and horizontally, whereby a gooseneck container, when loaded on the vehicle, is arranged with its corner fitting horizontally next to and adjacent to the locking housing, the horizontal locking bolt has a free end which, when unlocked, does not protrude laterally beyond the locking housing and, when locked, engages in a lateral opening in the corner fitting of the gooseneck container and secures the gooseneck container via the opening, and the wedge carriage is mounted so that it can be moved back and forth in the horizontal direction of movement of the horizontal locking bolt and is connected to the horizontal locking bolt, a double locking system is specified which can secure both conventional containers with a locking system that engages vertically from below and gooseneck containers, i.e. containers with a gooseneck tunnel with an actively driven horizontal locking system.

[0018] Alternatively, the wedge slide is mounted for reciprocating movement in a horizontal plane perpendicular to the direction of movement of the horizontal locking bolt, and the horizontal locking bolt is operatively connected to the wedge slide via a wedge slide. This also provides a double locking system that can secure both conventional containers with a vertical locking system engaging from below, as well as gooseneck containers, i.e., containers with a gooseneck tunnel with an actively driven horizontal locking system. Particularly preferred is the 90° deflection of movement from the wedge slide to the horizontal locking bolt, which creates a compact drive option that preserves valuable loading length on the vehicle.

[0019] If the drive has a double-acting pneumatic cylinder with a laterally movable piston rod, whereby the piston rod is operatively connected to the wedge slide in such a way that an idle stroke occurs during the first part of the stroke movement of the drive and the lateral movement of the wedge slide occurs during the second part of the stroke movement, the wedge slide is only actuated in the second part of the stroke movement.

[0020] By arranging a locking device on the locking housing, which has a spring-loaded lock that is designed to engage the lateral movement path of the wedge slide, the displacement of the wedge slide and thus of the horizontal locking bolt is achieved in a technically simple manner. The locking device activates a positive locking mechanism that prevents the locking device from being accidentally reopened, both with regard to the horizontal locking bolt and the locking bolt, by the lock in the movement path of the wedge slide.

[0021] Because the locking device has a release mechanism for the lock, which releases the lock during the idle stroke, it is possible for the locking device to be released during the idle stroke, i.e. in the first part of the stroke movement of the piston rod, so that the locking device can be opened from the locked state to the unlocked state.

[0022] In the event that there is insufficient compressed air resource and / or a fault in the compressed air supply or the pneumatic cylinder, an emergency release is provided with which the positive locking of the locking device can be unlocked.

[0023] In a further embodiment, the emergency release has two externally threaded push elements, the first of which can be screwed into a first threaded hole in the locking device and the second of which can be screwed into a second threaded hole in the locking housing. The first push element releases the lock and the second push element moves the wedge slide to open the lock. Thus, the locking device can be released with the first push element and the locking device can be adjusted from the locked to the unlocked state with the second push element, without the need for force via the pneumatic cylinder (emergency release). Accordingly, a container or even a gooseneck container can be unloaded by manually operating the emergency release in the event of a pneumatic failure.

[0024] Due to the fact that in the particularly compact design of the locking device with movement deflection by 90° the wedge slide has a second driver which engages in the wedge slide, wherein the wedge slide has an actuating bevel which cooperates with a bearing surface of the horizontal locking bolt for the axial movement of the horizontal locking bolt, the first horizontal, lateral movement of the wedge slide is converted via the actuating bevel in the wedge slide into a perpendicular, second horizontal movement of the axially displaceably mounted horizontal locking bolt, whereby the wedge slide can be actuated in a known manner by a hydraulic cylinder arranged in its direction of movement, without this drive causing a further shortening of the usable loading length.

[0025] If a second idle stroke is formed between the second driver and the wedge slide, which moves the wedge slide along when the wedge slide is actuated, and a contact surface arranged perpendicular to the direction of movement of the horizontal locking bolt is provided on the actuating bevel, which, together with the bearing surface of the horizontal locking bolt, blocks the horizontal locking bolt in the locked state, the horizontal locking bolt is mechanically locked against accidental retraction. When the drive is actively actuated to release the locking (adjustment from the locked to the unlocked state), this locking device first moves free and then the horizontal locking bolt is retracted into the unlocked state by sliding along the bearing surface on the actuating bevel. The gooseneck container can now be unloaded.

[0026] According to the method, the container locking method is characterized in that during a first part of the lifting movement of the drive an idle stroke is carried out and during a second part of the lifting movement the wedge slide is moved along, whereby when unlocking a container / gooseneck container from the locked state to the unlocked state during the first part of the lifting movement in the idle stroke the lock is released and then during the second part of the lifting movement the wedge slide and thus the horizontal locking bolt is moved back and in parallel the locking bolt is first raised and then turned back into the unlocked state.

[0027] Two embodiments of the invention are described in detail below with reference to the accompanying drawings.

[0029] In Fig. 1 A three-dimensional view of a first embodiment of the container locking device is shown, which is provided on a loading area of ​​a vehicle F, in particular at the front end of a gooseneck trailer, on which a container to be transported is to be placed. The locking device has a locking housing 1, which has a drive box 10 and a guide component 11 with a load-bearing surface 12 mounted thereon. The guide component 11 projects beyond the loading area. The upwardly projecting guide component 11 fits into a corner fitting of the container, whereby the container rests securely on the loading area, in particular the load-bearing surface 12. Alternatively, if a gooseneck container is loaded, it is loaded with its two front corner fittings resting against a locking housing 1 arranged there on the gooseneck trailer in a slightly lower position. The locking device is in Fig. 1 in the unlocked state, ready to load or unload a (gooseneck) container, and in Fig. 2 in the locked state, in which the (gooseneck) container is positively and force-locked to the loading area of ​​the vehicle (gooseneck trailer).

[0030] To lock the loaded container, a locking bolt 2 is provided, which is arranged in a central and vertical axis Z (see Fig. 4b ) is mounted axially displaceably and rotatably in the guide component 11. The locking bolt 2 has a cylindrical shaft 20 which is mounted and held axially displaceably and rotatably in the locking housing 1. Furthermore, the locking bolt 2 has a locking head 21 at the upper end of the shaft 20 which has a mushroom-shaped but elliptical contour and, in an unlocked state, rests congruently on the guide component 11 and can be adjusted into a locked state in which the locking head 21 is rotated by 90° and lowered, so that the projections now protruding from the elliptical locking head 21 beyond the guide component 11 engage behind the corner fitting of the loaded container.

[0031] For locking a gooseneck container loaded in a lower position laterally adjacent to the locking housing 1, a horizontal locking bolt 7 is provided, which can be moved in the horizontal direction of movement from a retracted position in the unlocked state ( Fig. 1 ), in which the horizontal locking bolt 7 does not protrude beyond the locking housing 1, into a forward position in the locked state, in which the horizontal locking bolt 7 protrudes with a free end 71 beyond the locking housing 1 and there engages laterally into an opening of the corner fitting of the gooseneck container.

[0032] The exact operation and the required components of the container locking device are described in the Fig. 3 bis 7 in a top view of the container locking device (each for part figure a) and a cross-section (each for part figure b).

[0033] In Fig. 3 The container locking device is shown in its unlocked state, in which a container can be unloaded or loaded. This can be seen from the fact that the locking bolt 2 with its shaft 20 is in an elevated position, i.e., axially displaced upwards, and the locking head 21 belonging to the locking bolt 2 rests on the guide component 11, as can be seen in particular from Fig. 3b can be seen. Accordingly, a container with its corner fitting and its slot-like opening formed therein can be loaded onto the loading area and in particular onto the load-bearing surface 12 via the locking head 21 and the guide component 11 or lifted from the loaded position, since the locking head 21 is aligned with the guide component 11 (see top view). Fig. 3a ). Furthermore, the horizontal locking bolt 7 is in its retracted position, in which the horizontal locking bolt 7 does not protrude beyond the locking housing 1.

[0034] Furthermore, Fig. 3a A top view of the drive 3 in the form of a double-acting pneumatic cylinder 30 can be seen, which is arranged in the drive box 10 of the locking housing 1. The double-acting pneumatic cylinder 30 has a piston rod 31, which interacts via a drive claw 32 with a wedge slide 4, which can be moved back and forth in the drive box 10 parallel to the pneumatic cylinder 30, via a driver 41. With regard to the design of the wedge slide 4 and its operative connection to the locking bolt 2, reference is made to the as yet unpublished DE 10 2021 112 894 of the same applicant, as to how the required rotary movement of the shaft 20 and thus of the locking head 21, as well as the lowering and re-raising, are realized.

[0035] When the pneumatic cylinder 30 is actuated and the locking device is thus moved from the unlocked state to the locked state, the piston rod 31 with the drive claw 32 initially moves from the Fig. 3b shown position in the plane of the drawing to the left, as compared with Fig. 4b The driver 41 is driven by the drive claw 32, whereby the wedge slide 4 connected to the driver 41 also moves in the plane of the drawing according to Fig. 4b to the left or in drawing plane according to Fig. 4a downwards. Since the horizontal locking bolt 7 is attached to the wedge slide 4 directly in the extension of its horizontal direction of movement, it also moves in this horizontal direction of movement and, as can be seen from the Fig. 4a und 4b As can be seen, it already protrudes a little beyond the locking housing 1. Parallel to this, the shaft 20 of the locking bolt 2 rotates and thus also begins to move toward the locked state.

[0036] In Fig. 5 the further movement sequence in the direction of the locked state is shown, whereby the piston rod 31 of the pneumatic cylinder 30 is extended even further and thus, via the drive claw 32 and the driver 41, the wedge slide 4 is moved even further in the horizontal direction of movement H (in Fig. 5a downwards). Accordingly, the free end 71 of the horizontal locking bolt 7 protrudes even further and, in parallel, the locking head 21 is turned even further to the left (see Fig. 5a compared to Fig. 4a ).

[0037] In Fig. 6 the locked state is then reached, in which the locking head 21 is now rotated by 90 ° and lowered between the guide component 11 (see Fig. 6a und 6b ). Parallel to this, the horizontal locking bolt 7, with its free end 71 also protruding far, can be seen in its locked state. In this locked state, the free end 71 of the horizontal locking bolt 7 can engage laterally in a corner fitting of a gooseneck container, thus securely fixing it.

[0038] Furthermore, reference is made to a locking device 5 which is arranged in the drive box 10 of the locking housing 1 and has a lock 51 which, via a leaf spring 52, bears against the drive claw 32 or the driver 41, so that when the end position is reached in the locked state ( Fig. 6b ) engages in the path of the wedge slide 4, namely behind the driver 41, and there forms a positive lock against an undesired release (resetting) of the locking mechanism.

[0039] To release the container lock from the locked state back to the unlocked state, starting from Fig. 6 (locked state) the double-acting pneumatic cylinder 30 is activated to retract the piston rod 31, which initially results in a short idle stroke of the piston rod 31, during which the drive claw 32 moves from its the driver 41 in the plane of the drawing from Fig. 5b pushing position to the left in which the driver 41 in the plane of the drawing from Fig. 7b to the right pulling position and comes into contact with a displacement component 53 of the locking device 5 by means of a trigger projection 33 on the drive claw 32.

[0040] During the further movement, namely the further retraction of the piston rod 31 into the pneumatic cylinder 30, the release projection 33 on the drive claw 32 via the displacement component 53 of the locking device 5 releases the lock 51 against the force of the leaf spring 52 from the movement path of the driver 41 (in the plane of the drawing of the Fig. 6b and 7b upwards), whereby the driver 41 and thus the wedge slide 4 in the drive box 10 is released and the driver 41 prevents the lock 51 loaded by the leaf spring 52 from springing back. The locking bolt 2 is thereby raised completely in the axial direction, so that the projections of the locking head 21 are above the guide component 11 ( Fig. 7b ) and now the reverse rotation of the locking head 21 takes place, as can be seen from the comparison of the Fig. 6b can be seen with 7b, where the locking bolt 2 is raised and already slightly turned back.

[0041] The return movement of the wedge slide 4 also retracts the horizontal locking bolt 7, so that the unlocked state is then restored according to Fig. 3 Accordingly, the locking bolt 2 rotates back into its unlocked state so that the locking head 21 is aligned with the guide component 11, as shown in Fig. 3a shown in top view (unlocked state).

[0042] Furthermore, an emergency release 6 (in the Figuren 3b bis 7b only indicated by screw 61), whereby the screw 61 interacts with the locking device 5, so that when screwing in the screw 61, the lock 51 is moved out of the lateral movement path of the driver 41 against the force of the leaf spring 52. Now, with a thrust element not shown here, the no longer locked wedge slide 4, for example in case of failure of the compressed air supply or damage to the pneumatic cylinder, can be manually moved into its unlocked state according to Fig. 3a and b are reset.

[0043] The Figuren 8 bis 14 The container locking device shown in the second embodiment is designed analogously to the first, so that in this respect reference is made to the first three paragraphs of the figure description for the first embodiment.

[0044] For locking a gooseneck container loaded in a lower position laterally adjacent to the locking housing 1, a horizontal locking bolt 7 is provided, which in the first horizontal direction of movement from a retracted position in the unlocked state ( Fig. 8 ), in which the horizontal locking bolt 7 essentially does not protrude beyond the locking housing 1, into a forward position in the locked state ( Fig. 9 ), in which the horizontal locking bolt 7 projects with a free end 71 significantly beyond the locking housing 1 and engages there laterally into an opening of the corner fitting of the gooseneck container.

[0045] The exact operation and the required components of the container locking device are described in the Fig. 10 bis 14 in a side view (each relating to part a), a top view (each relating to part b) of the container locking device and a cross-section (each relating to part c).

[0046] In Fig. 10 The container locking device is shown in its unlocked state, in which a container can be unloaded or loaded. This can be seen from the fact that the locking bolt 2 with its shaft 20 is in an elevated position, i.e., axially displaced upwards, and the locking head 21 belonging to the locking bolt 2 rests on the guide component 11, as can be seen in particular from Fig. 10a can be seen. Accordingly, a container with its corner fitting and its slot-like opening formed therein can be loaded onto the loading area and in particular onto the load-bearing surface 12 via the locking head 21 and the guide component 11 or lifted from the loaded position, since the locking head 21 is aligned with the guide component 11 (see top view). Fig. 10b ). Furthermore, the horizontal locking bolt 7 is in its retracted position, in which the horizontal locking bolt 7 does not protrude significantly beyond the locking housing 1.

[0047] Furthermore, Fig. 10b In plan view, the drive 3 can be seen in the form of a double-acting pneumatic cylinder 30, which is arranged in the drive box 10 of the locking housing 1. The double-acting pneumatic cylinder 30 has a piston rod 31, which interacts via a drive claw 32 with a wedge slide 4, which can be moved back and forth in the drive box 10 parallel to the pneumatic cylinder 30, via a first driver 41. With regard to the design of the wedge slide 4 and its operative connection to the locking bolt 2, reference is made to the as yet unpublished DE 10 2021 112 894 of the same applicant. How the required rotational movement of the shaft 20 and thus of the locking head 21 is realized can be seen from the sectional view. Fig. 10c visible.

[0048] When the pneumatic cylinder 30 is actuated and the locking device is thus moved from the unlocked state to the locked state, the piston rod 31 with the drive claw 32 initially moves from the Fig. 10b shown position in the plane of the drawing to the left, as compared with Fig. 10b The first driver 41 is driven by the drive claw 32, whereby the wedge slide 4 connected to the first driver 41 also moves in the plane of the drawing according to Fig. 10b to the left. A second driver 42 is formed or attached to the wedge slide 4, which moves a wedge slide 8 on the locking housing 1 in the same first horizontal direction of movement (H 1 ), i.e. in Fig. 10b and 11bto the left. An actuating bevel (81) formed on the wedge slide (8) interacts with a bearing surface (72) on the horizontal locking bolt 7, whereby the latter moves in a second horizontal direction of movement (H 2 ) 90° to the first horizontal direction of movement (H 1 ) and, as can be seen from Fig. 11b As can be seen, it already protrudes significantly beyond the locking housing 1. Parallel to this, the shaft 20 of the locking bolt 2 rotates and thus also begins to move toward the locked state.

[0049] In Fig. 12 the locked state is then reached, in which the locking head 21 is now rotated by 90 ° and lowered between the guide component 11 (see Fig. 12a und 12b ). Parallel to this, the horizontal locking bolt 7 with its free end 71 can also be seen projecting far in its locked state. When the locked state is reached, the wedge slide (4) and thus the wedge slide (8) slide out in the plane of the drawing according to Fig. 12 completely to the left, the bearing surface (72) of the horizontal locking bolt 7 along the actuating bevel (81) of the wedge slide (8) to its outer edge, until the bearing surface (72) of the horizontal locking bolt 7 rests on the support surface (82) of the actuating bevel (81) (see Fig. 12c ). In this locked state, the free end 71 of the horizontal locking bolt 7 can engage laterally in a corner fitting of a gooseneck container and thus securely fix it, since the horizontal locking bolt 7 is secured against unintentional retraction counter to the second horizontal direction of movement (H 2 ) by the positive engagement of the bearing surface (72) of the horizontal locking bolt 7 on the support surface (82).

[0050] Furthermore, reference is made to a locking device 5 which is arranged in the drive box 10 of the locking housing 1 and has a lock 51 which, via a leaf spring 52, bears against the drive claw 32 or the driver 41, so that when the end position is reached in the locked state ( Fig. 12b ) engages in the path of the wedge slide 4, namely behind the driver 41, and there forms a positive lock against an undesired release (resetting) of the locking mechanism.

[0051] To release the container lock from the locked state back to the unlocked state, starting from Fig. 12 (locked state) the double-acting pneumatic cylinder 30 is activated to retract the piston rod 31, which initially results in a short first idle stroke of the piston rod 31, during which the drive claw 32 moves from its first driver 41 in the plane of the drawing from Fig. 11b pushing position to the left into which the first driver 41 in the plane of the drawing Fig. 13b to the right pulling position and comes into contact with a displacement component 53 of the locking device 5 by means of a release projection 33 on the drive claw 32. In parallel, a second idle stroke is carried out between the second driver (42) and the wedge slide (8), so that the return movement of the wedge slide (8) in Fig. 13c opposite to the first horizontal direction of movement (H 1 ) just begins and the positive engagement of the bearing surface (72) of the horizontal locking bolt 7 on the support surface (82) is released.

[0052] During the further movement, namely the further retraction of the piston rod 31 into the pneumatic cylinder 30, the release projection 33 on the drive claw 32 via the displacement component 53 of the locking device 5 releases the lock 51 against the force of the leaf spring 52 from the movement path of the first driver 41 (in the plane of the drawing of the Fig. 13b and 14b upwards), whereby the first driver 41 and thus the wedge slide 4 in the drive box 10 is released and the first driver 41 prevents the lock 51 loaded by the leaf spring 52 from springing back. The locking bolt 2 is thereby raised completely in the axial direction, so that the projections of the locking head 21 are located above the guide component 11 ( Fig. 14a ) and then the locking head 21 can be turned back.

[0053] Due to the return movement of the wedge slide 4, the horizontal locking bolt 7 is then also retracted with the parallel return movement of the wedge slide (8) via the actuating bevel (81) of the wedge slide (8), so that the unlocked state according to Fig. 10 Accordingly, the locking bolt 2 rotates back into its unlocked state so that the locking head 21 is aligned with the guide component 11, as shown in Fig. 10b shown in top view (unlocked state).
